1 Claim.

This invention discloses a light projector, divided out of my pendingapplication Serial No. 252,228, filed January 21, 1939.

This invention aims to provide a new and useful lamp for use onautomobiles and similar vehicles, the construction being such that thelamp may be located below the bumper of the vehicle, to throw light downon the road without illuminating the fog above an elevation representedby the bumper, to the discomfort of the driver of the car. Anotherobject of the invention is to supply a device of the class describedwherein a deflector, associated with the lamp, may be adjusted about alongitudinal axis, to throw light on the roadway at different places,considered transversely of the line of advance of the vehicle. A furtherobject of the invention is to improve the lamp construction.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

With the above and other objects in View, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the drawing:

Fig. 1 is a side elevation;

Fig. 2: is a longitudinal section;

Fig. 3 is a cross section; and

Fig. 4 is a bottom plan, parts being broken away in Figs. 2: and. 4.

In carrying out the invention, there is provided a tapered lamp body I,the body I having a spherical boss 29 on its rear end. The forward endof the body I is reduced in diameter to fashion a neck 2. The neck 2 issupplied with a hollow outstanding bead 3. The bead 3 extends but partway around the neck 2, as the dotted line showing of Fig. 2 will makemanifest. Opposite to the bead 3, the neck 2 is inset to form a seat 4.A reflector 5 is disposed within the body I. The reflector 5 has aflange overlapping the forward end of the neck 2. The numeral 6 marks alens. The lens 6 has an annular marginal recess I. A resilient gasket 8is mounted in. the recess I. The gasket 8 may be considered as part ofthe lens 6. The gasket 8 abuts against the flange at the forward end ofthe reflector 5.

65 A retaining ring 9 extends around the neck 2 of the lamp body I andhas a flange overlapping the forward surface of the lens 6. Theretaining ring 9 has a hollow circumferential head III. The bead 3 andthe neckZ on the lamp body I are received in the bead IU of theretaining ring 9. Because the bead 3 of the neck 2 extends but a shortdistance around the neck, the bead 3 can be received in the bead III ofthe retaining ring 9, and then the part of the retaining ring 9 that isnot adjacent to the bead 3 can be pushed back 10 into place, as shown inFig. 1.

One flange of an angle bracket 22 is secured to the retaining ring 9.The purpose of the seat 4 in the neck 2 of the lamp body I is to receivesaid flange of the angle bracket 22, and set the 15 angle bracketinwardly to such an extent that the retaining ring 9 will not be humpedaway from the neck 2 of the body. An angle bracket 23 is secured to thebody I. The angle brackets 22 and 23 are connected by a draw screw 24.20 When the screw 24 is tightened up, the retaining ring 9 will be heldin the position shown in Fig. 1.

The numeral II marks a cylindrical deflector having transversereinforcing ribs 19. The deflector II is open at its forward end, and ispro- 25 vided with a longitudinal opening I2 extended from one end ofthe deflector to the other. The rear end of the deflector II extendsaround the retaining ring 9 and has a circumferential, hollow bead I 4,receiving the bead III of the retaining 30 ring 9.

A gripping band I5 extends around the rear end of the deflector II. Thegripping band I5 has a longitudinal bead I6. The bead I6 of the grippingband I5 receives the bead I4 on the rear 35 end of the deflector I I. Atone end, the gripping band I5 has a hook IT. A bowed connector I8 isprovided. The connector I8 is supplied at one end with a hook I9. At itsopposite end, the connector I9 is equipped with an oflset finger 40piece 20.

A keeper 2|, in the form of a link, is pivoted to the intermediateportion of the connector I8, and to the adjacent end of the grippingband I5.

When the hook I! of the gripping band I5 45 is engaged with the hook I9of the connector I8, and when the keeper 2| is swung back against theband l5, as in Fig. 2, the band Will be held tightly about the deflectorII, and the deflector, in turn, will be held against rotation on the re-50 taining ring 9. By means of the finger piece 29, the operator canloosen the connector I8, slacking away'the resilient gripping band I5and, then, the deflector II can. be rotated about its axis, thereby toshift the position of the opening I2 in the deflector, so that theopening will permit light to be thrown downwardly toward the surface ofthe road, inwardly toward the longitudinal center of the road, orlaterally, as occasion may require.

The reflector 5 has a tubular neck 25, in which is mounted a socket 26,carrying an electric lamp 21. The numeral 34 designates, generally, anysuitable means engaged with the spherical boss 29, at the rear end ofthe lamp body I, to support the lamp body either above or below thebumper of a vehicle, or to carry the lamp body in any other positionwhich the operator may require.

The device forming the subject matter of this application is simple inconstruction but will be found thoroughly advantageous for the ends inview.

Having thus described the invention, what is claimed is:

In a lamp construction, a body having a bead extended part-way aroundthe body, a lens, a retaining ring having a circumferential bead engagedwith the bead of the body, the body being inset in remote relation tothe bead, to form a seat, an angle bracket one flange of which isconnected to the ring and received in the seat to prevent the ring fromrotating, a draw connection between the other flange of the bracket andthe body, a tubular deflector having a longi-- tudinal opening extendedthe full length of the deflector, the deflector being provided with atransverse bead engaged with the bead of the ring and permitting acircumferential adjustment of the deflector whilst the ring is heldagainst rotation by the first-specified flange of the angle bracket, anda tightening band ex- ,tended about the deflector and provided with atransverse bead receiving the bead of the defiector.
